请帮我解决这个问题。

好的。我在附近挖了一些,看起来这是一个

该缺陷在2.0.3版中标记为“已解决”,但尚未发布

编辑:OP已将降级至1.2.3版报告为临时解决方案:

pip install -U --allow-external mysql-connector-python mysql-connector-python==1.2.3

我以前从未见过那个数据库引擎。在我新安装的Django 1.7中,它显示了'ENGINE':'Django.db.backends.mysql'数据库引擎的配置如下,mysql连接器python确实导致了这个问题。版本2.0.3尚未发布,因此我将mysql连接python降级为版本1.2.3。它解决了这个问题。多谢各位
